Slicing Machine Motor Tower with Detachable Rotor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slicing machines require a significant amount of time and effort to mount and align the drive motor, making the process cumbersome and prone to dirt and liquid exposure.
Innovation Solution
A slicing machine design where the rotor is detachable from the stator, allowing the stator to be fixed inside the machine housing and the rotor inserted from outside, with an attachment device for easy fastening, enabling simplified motor installation and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the drive motor is mounted and aligned in the machine housing using conventional methods, then the motor is securely positioned, but the process requires a great deal of time and effort
Solution Approach 1:
The drive motor is divided into two separable components: the stator (stationary part) and the rotor (rotating part). The stator is mounted in the machine housing first, and the rotor is inserted separately through the insertion opening. This segmentation allows independent positioning and simplifies the overall assembly process, reducing mounting and alignment time.
Solution Approach 2:
The rotor is extracted from the stator assembly and inserted through the insertion opening in the machine housing. This extraction allows the rotor to be positioned independently and simplifies the mounting process, as the rotor can be inserted from the outside rather than requiring complex alignment with the stator already in place.
2Reliability
If the motor shaft projects through the housing toward the blade axis, then the blade can be driven, but the region is difficult to seal against dirt and liquid
Solution Approach 1:
The rotor, which contains the motor shaft, is extracted and inserted through the insertion opening rather than having the shaft project through the housing. This allows the housing to be sealed more effectively, as the rotor can be positioned inside the housing without requiring external shaft projections that are difficult to seal.
Solution Approach 2:
The rotor is nested within the stator assembly inside the machine housing. The rotor fits into the stator, and both are contained within the sealed housing environment. This nesting arrangement allows the motor components to be housed together in a sealed enclosure, protecting them from dirt and liquid while maintaining functional integrity.

AI summary
A slicing machine cuts slices of cutting material. The slicing machine has: a machine housing holding a motor and circular blade driven by the motor; a product feed, which feeds the cutting material to the circular blade; a stop plate; and a slidably arranged carriage, which feeds the cutting material to the blade. The blade is mounted directly on a bearing shaft arranged in the drive motor for the circular blade. The drive motor includes at a stator and rotor, which is detachable from the stator. The stator is in the machine housing. The machine housing has an insertion opening where, in the assembled state, the stator is arranged and through which the rotor is at least partially inserted into the stator. The slicing machine has an attachment device comprising at least one fastener that is configured to fasten the rotor and the stator to the machine housing.
